| Date:		May 2012

| KernelVersion:	v3.5

 | |
| Description:	/sys/kernel/iommu_groups/ contains a number of sub-
 | |
| 		directories, each representing an IOMMU group.  The
 | |
| 		name of the sub-directory matches the iommu_group_id()
 | |
| 		for the group, which is an integer value.  Within each
 | |
| 		subdirectory is another directory named "devices" with
 | |
| 		links to the sysfs devices contained in this group.
 | |
| 		The group directory also optionally contains a "name"
 | |
| 		file if the IOMMU driver has chosen to register a more
 | |
| 		common name for the group.
